Ground Penetrating Radar Systems’ Memphis, TN office worked with a construction company to scan for and locate underground utilities before ground disturbing activities. GPRS uses non-destructive testing equipment to locate piping, power-lines, underground storage tanks, and grave sites that are unable to be seen. Using GPRS is a safe, cost effective way to make sure you can safely drill or dig and not destroy any underground utilities or determine if USTs do or do not exist on a property.
